Hello,
I'm trying to follow
http://www.ovirt.org/develop/release-management/features/infra/python-sdk/ and I'm successfully discovering Python + oVirt SDK on CentOS.
I'd like to do the same on Ubuntu, but the instructions seem incomplete :
" easy_install ovirt-engine-sdk-python "
is working, but "import ovirtsdk" doen't give anything.
Note that the wiki page is about SDK version 3, which will be deprecated in 4.2. When you run 'easy_install ovirt-engine-sdk-python' it will install Python SDK version 4, which is different from SDK version 3.
You're right, and I haven't noticed : import ovirtsdk4 is working.
You may find few examples of Python SDK version 4 here:
https://github.com/oVirt/ovirt-engine-sdk/tree/master/sdk/examples
Yes, this list of examples is a treasure, and I'm grateful to the maintainers.
Alas, though we already have one DC in V4, most of our production DCs are still in V3 for one year, and I have to maintain them. So far, I have no clue how to add ovirtsdk v3 to my Ubuntu. You just need to specify which version you would like to install, in your case:
easy_install ovirt-engine-sdk-python==3.6.9.2 eactly the same with pip
pip install ovirt-engine-sdk-python==3.6.9.2
Another point : is the compatibility between ovirtsdk and oVirt completely obvious (ie 3 -> 3 and 4 -> 4), or is there any kind of backward compatibility? Unfortunatelly no, there is no backward compatibility between SDK v3 and v4.
Just to clarify this:
1. Version 3 of the SDK only works with version 3 of the API.
2. Version 4 of the SDK only works with version 4 of the API.
3. Version 3 of the engine only supports version 3 of the API.
4. Versions 4.0 and 4.1 of the engine support both version 3 and 4 of the API. This means that with version 4 of the engine you can use both versions of the SDK. This will change with version 4.2 of the engine. There we will remove support for version 3 of the API, so you will need to use version 4 of the SDK.
